To all whom-it may concern:

Be it known thatL-finnnrN; HEWLETT, of Oscoda, in the county of .Ios coand State of Michigan, have invented a new and nsefuln ;en g\ ines inon nted on V a frame, which =r'nay be; "providedwith-wheels for portability, and the enginesarecozinectedjwith a crankshaft-27, "on which-is-secured a pinion, 35., '1

Improvement in Log-skidding and Loading Machines, of which the following isaspeci'fi-l cation. f My invention consists in an improvement in log skidding and loading machines, hereinafter fully described and pointed out. Figure 1 is a side elevation, and Fig. 2 a plan view, of the complete apparatus. Fig.3 is an elevation of-the drum-gears. Fig. .4'is a vertical central section through the drag-rope clutch. Fig. 5 isa longitudinal section through one of the winding-drums. f" 1 and 3 represent strong posts ortre'es which in 'actuai operation are Lobe well sup-'" ported by guy-ropes. 9 represents an end-lesstra-ck passed through blocks 7 and 8, and made endless .by-Jbein'g secured to a carrier, 18, at the poin'ts23' 24. 'The endless track is stretched between trees land 3 by securing theblocks 7 8 to said trees by chains or ropes, asshown'in Fig.- 1, andshonldbe stretched at' consider-ah'ledistance from the ground,- and as as-its length-and weight will permit.

Any known method ,of forcing theloose":

On the shaft: which'ca-rries gear-wneelfi? I put two loose dllllllS, i'qlS, shown in Fig. 5, to'

the track, 9 being stretched betweeutre'esl'l and 3; the carrier 18, carrying wltll 'ib l-hef drag-rope 10, is run'out to the end of the.

track by winding in rope 29,.which draws; the, upper half' of track ,9 -toward block 8,

fand of course. moves the lower half of -.the:.

' 7 track, in which is carrier 18, in the contrary,

direction. When the carrier is at the end of, or. other desired point. on, the track.-

drum 28, which 'actuates' rope29, is stopped, leaving the carrier stationary. -'1 he' end of i drag-rope 10 is now carried to a log which it is-desired to haul in, and the tongs 17 at tached to saidlog. Drum 26 is now clutched tojits shaft and the-drag-rope hauled'in, bringinzwith lit the log to which it is. attached, 4.

As the ropes 30 and 31 are comparativelyshort', they can be op- :erated by a single shaft carrying two loose drums, and this is provided for by the con-" struction shown in Fig. 5, in' which the, two short; drums 86116 131 operate the ropes 30 and 31.

, The operation of the leadingdevice is'pre I c'is'ely .like'thatof the skidding device herein- I am aware that the use of carriers running on suspended tracks and carrying drag-ropes, by whicha .w-eight'can be raised and then .drawn inover the track, is quite old, and has been used in carrying water,-hay, logs, &c., and thereforedonot claim the same.
